Procedure

In analogy to the procedure described in example 20b, 4-chloro-2,6-bis-(2-hydroxy-ethylamino)-pyrimidine-5-carbonitrile was treated with 1-(2-ethyl-phenyl)-piperazine in dioxane in the presence of N-ethyl-diisopropylamine at 60° C. to yield 4-[4-(2-ethyl-phenyl)-piperazin-1-yl]-2,6-bis-(2-hydroxy-ethylamino)-pyrimidine-5-carbonitrile as an amorphous, light brown solid; MS: [M+H]+=412.
